Name of Applicant: Balcke-Durr Aktiengesellschaft Actual Inventor(s): Burkhard Trage Richard Leitz Georg Schrey Address for Service: PHILLIPS ORMONDE FITZPATRICK Patent and Trade Mark Attorneys 367 Collins Street Melbourne 3000 AUSTRALIA Invention Title: NATURAL DRAFT COOLING TOWER Our Ref 312971 POF Code: 1509/26135 The following statement is a full description of this invention, including the best method of performing it known to applicant(s): -1- 6006 NATURAL DRAFT COOLING TOWER Background of the Invention The present inventior relates to a natural draft cooling tower with a plurality of heat exchanger elements, preferably in the shape of a pitched roof, for condensing turbine exhaust steam of a power plant, wherein the heat exchanger elements, supplied with the exhaust steam by a common central steam inlet line and radially extending distributing lines, operate in part in a condensational and in part in a dephlegmational manner, with the dephlegmationally operating heat exchanger elements arranged downstream of the condensationally operating heat exchanger elements, the heat exchanger elements distributed Sover a plurality of identical sectors, each sector ;i having complete lines for steam distribution as well as inert gas and condensate removal lines.
i Such natural draft cooling towers for condensation of turbine exhaust steam of a power plant are known from German Offenlegungsschrift 34 41 514. Since the collection of inert gases 440 '4t within the heat exchanger elements must be prevented, the final condensation is performed in the dephlegmationally operating, forced-vented -lfl-- I_ __I
C
heat exchanger elements from which the inert gases are removed. In order to provide the dephlegmationally operating heat exchanger elements with a sufficient amount of cooling air during all conceivable load situations and during unfavorable weather conditions, these dephlegmationally operating heat exchanger elements are provided with their own fans. These fans ensure a complete final condensation of the entire turbine exhaust steam to be condensed within the dephlegmationally operating heat .44 exchanger elements even under unfavorable weather 9o4 conditions such as strong lateral winds and a inversion situations and provide also the option 4 oo that, due to the resulting additional draft power 0 within the cooling tower that is otherwise operated only by natural draft, the cooling tower shell can be designed with a respectively reduced height to thereby lower construction costs.
oa From German Auslegeschrift 19 60 619 a symmetrically designed natural draft cooling tower is known in which the heat exchanger elements which are essentially in the shape of a pitched roof are arranged radially with respect to the longitudinal axis of the cooling tower. The steam 2 to be condensed is supplied via a centrally arranged steam inlet line from which radially extending steam distribution lines branch off to the ridge of the respective pitched roof-shaped heat exchanger elements. These operate in part in a condensational and in part in a dephlegmational manner whereby the dephlegmationally operating heat exchanger elements are arranged on an inner circle about the steam inlet line. One dephlegmationally operating heat exchange element is coordinated with two condensationally operating heat exchanger elements which are arranged in the o .o0. radial extension of the dephlegmational heat *0 *4 o. exchanger element so that essentially an 0* arrangement of heat exchanger elements within individual segments results. All of the heat exchange elements as well as their corresponding a lines are arranged on a single common support construction which is supporter' on shoulders of the outer shell of the natural draft cooling tower.
From German Offenlegungsschrift 24 05 999 a natural draft cooling tower with a radial arrangement of the individual heat exchanger elements is known. The condensationally operating 3 heat exchanger elements are arranged on an outer circle and the dephlegmationally operating heat exchanger elements are arranged on an inner circle close to the central steam inlet line. The arrangement of the condensationally operating heat exchange elements is two-stepped. A first condensational step is embodied by heat exchanger elements arranged adjacent to the outer wall of the cooling tower, and a second condensational step is provided by heat exchanger elements radially inwardly arranged and staggered relative to the heat exchanger elements of the first step.
The second step is on a lower level than the first step. The heat exchanger elements of the second condensational step thus take over the remaining steam of two neighboring heat exchanger elements of the first condensational step. It is disadvantageous in this embodiment that due to the connection of the condensational heat exchanger elements with the respective neighboring radially displaced heat exchanger elements a reduced operation of the device with only a portion of the total number of heat exchanger elements present is not possible.

Ger-man Offenlegungsschrift 22 42 058 condensationally operating heat exchanger elements are arranged on a plurality of circles about the central longitudinal axis of the cooling tower.
The steam to be condensed is fed via steam inlet lines circularly arranged about the central longitudinal axis of the cooling tower. All heat exchanger elements of one circular arrangement are positioned on a common support construction in order to provide a staircase-like arrangement in the radially outwardly oriented direction by selecting respective suitable heights for the various circular arrangements.
a t o Based on the disclosure of German o« Auslegeschrift 19 60 t19 it is therefore an object a* a of the present invention to provide a natural draft cooling tower which provides for a favorable au a Sadaptation of the respective condensation power to different operational conditiois and/or +-o changing weather conditions and which, at the same time, provides for an optimal use of the base surface area of the cooling tower.

Brief Description of the Drawings This object, and other objects and advantages of the present invention, will appear more clearly 5 r from the following specification in conjunction with the accompanying drawings, in which: Fig. 1 is a side view of a first embodiment of the arrangement of the heat exchanger elements in a cross-section along the line I-I in Fig. 2; Fig. 2 is a plan view of the heat exchanger elements according to the section II-II in Fig.
1; Fig. 3 is a representation o corresponding to Fig. 1 of a o00004 second embodiment; 0 0 Fig. 4 is a further representation according to Figures 1 and 3 Su oo 0 0 of a third embodiment; and Fig. 5 is a further embodiment •according to Figures 1, 3, and 4.
it Summary of the Invention The natural draft cooling tower of the present invention is primarily characterized by: Identical sectors assembled to form the 6 cooling tower; A central steam inlet line terminating in radial distributing lines extending in a radial plane, each sector having one of the radial distributing lines; Each sector having first heat exchanger elements operating in a condensational manner and second heat exchanger elements operating in a dephlegmational manner, with the second heat exchanger elements arranged downstream of the first heat exchanger elements, the second heat exchanger elements each having a fan; Each sector having an inert gas line connected to the second heat exchanger elements and a condensate removal line connected to the first and the second heat exchanger elements; and Each sector comprising an independent support frame for supporting the first and the second heat exchanger elements, with the first heat exchanger elements connected to the support frame such that a longitudinal axis of each first heat exchanger element is perpendicular to the radial distributing line and extends in a plane parallel to the radial plane of the radial distributing lines.
7 Due to the inventive embodiment of a natural draft cooling tower it is achieved that the lotyitudinal dimensions of the heat exchanger elements which are preferably shaped in the form of a pitched roof can be selected to different length corresponding to their arrangement on the support frame which is identical for all sectors.
Accordingly, an almost complete coverage of the sectors with heat exchanger elements is achieved so that the remaining free space is reduced to a minimum.
In a preferred embodiment of the present invention the first and the second heat exchanger elements have the shape of a pitched roof.
Preferably, each first heat exchanger element has a radially outwardly extending portion and a radially inwardly extending portion with respect to the ridge of the pitched roof, with the radially outwardly extending portion having a greater longitudinal dimension than the radially inwardly extending portion. With this preferred .embodiment the free space, respectively, the unused base surface area is further reduced.
With the inventive design of the natural draft cooling towers a considerable simplification 8 j of the construction and required calculations of natural draft cooling towers used for the condensation of turbine exhaust gas results because only one of the sectors of the cooling tower comprised of a plurality of sectors must be calculated and constructed. The identically designed and constructed sectors encompass respectively the corresponding number of condensationally and dephlegmationally operating heat exchanger elements corresponding to the respective share of heat exchanger elements per sector and include complete lines for the steam go c, distribution and for the removal of inert gas and i a* condensate, whereby the heat exchanger elements •and the complete lines are arranged on respective separate support frames and a connection or attachment of the separate sectors is only provided by their connection into the centrally arranged steam inlet line. With the inventive natural draft cooling tower it is thus sufficient SJ to calculate and construct only one of the sectors which represents essentially a building block for l the cooling tower. This results at the same time in a reduction of the expenditure for the manufacture and assembly of the cooling tower 9 because a plurality of identical sectors are manufactured and assembled so that manufacturing and assembly costs are reduced. Further advantages result for the operation of the inventive natural draft cooling tower because the independent sectors can be individually operated and switched on or off and can be adapted with respect to their cooling capacity so that especially an advantages adaptation of the respective condensation capacity to different Irr operational conditions and/or to changing weather t conditions is possible.
1111*3 .;In a further embodiment of the present invention the cooling tower shell is in the form of a steel construction whereby the cooling tower shell comprises a shell segment for each sector and wherein each support frame further supports the respective shell segment of the corresponding sector. This inventive embodiment a foundation for the cooling tower shell is eliminated. This 3 1.
design further reduces the manufacturing costs for the inventive natural draft cooling tower because the support frames of the individual sectors simultaneously serve to support the steel construction of the cooling tower shell.

Preferably, the cooling tower shell has the shape of a closed polygon. This shape, which is the approximation of a circular base surface area, provides for a uniform loading of the heat exchanger elements with cooling air and prevents the formation of preferred or unfavorable wind directions. The heat exchanger elements in this embodiment are essentially arranged on a plurality of imaginary rings or circles with respect to the longitudinal axis of the cooling tower shell.
Preferably, the second heat exchangers are arranged such that a longitudinal axis of each second heat exchanger element is parallel to the longitudinal axis of the first heat exchanger elements.
In an alternative embodiment the second heat exchangers are connected to the support frame directly adjacent to the central steam inlet such that a longitudinal axis of each second heat exchanger element extends radially. Thus, the condensationally operating heat exchanger elements are arranged parallel to one another with their steam distributing chambers essentially positioned at the ridge of the pitched roof-shaped heat exchanger elements, extending in the same F C 11 longitudinal direction and essentially forming a secant to the centrally arranged steam inlet line, whereby the dephlegmationally operating heat exchanger elements with their suction chambers positioned at the ridge of the pitched roof extending radially and located immediately adjacent to the steam inlet line on the support frame. This embodiment is advantageous with respect to guiding the remaining steam between the condensationally operating and the dephlegmationally operating heat exchanger elements.
In order to improve the resistance of the *a St natural draft cooling tower with respect to lateral winds, the heat exchanger elements of each sector are arranged in a plane that is upwardly Ca a slanted from the central steam inlet line in the radially outward direction.
"Description of Preferred Embodiments The present invention will now be described in detail with the aid of several specific embodiments utilizing Figures 1 through A first embodiment represented in Figures 1 and 2 is a natural draft cooling tower encompassing a plurality of pitched roof-shaped 12 ___lii heat exchanger elements 1, 2 connected to a steam inlet line 3 for condensing turbine exhaust steam of a non-represented power plant. The end portion of this steam inlet line 3 extends vertically in the center of the cooling tower and is connected to radially extending distributing lines 4, each coordinated with a respective sector S of the cooling tower, as can be seen especially in Fig.
2. In the embodiment of Figures 1 and 2, the cooling tower is made of six identical sectors S.
.o Via the central inlet line 3 and a respective radial distributing line 4 the steam to be o condensed is guided into two condensationally o o operating heat exchanger elements 1 connected in parallel to one another. With these °o condensationally operated heat exchanger elements 4 6 1 the major portion of the steam is condensed.
The remaining steam loaded with inert gases is a a guided via the collecting lines 5 into the distributing chambers 6 of the dephlegmationally 44 0 o o operating heat exchanger element 2 arranged downstream of the condensationally operating heat exchange elements 1. The distributing chambers 6 are arranged at the bottom of the dephlegmational operating heat exchange element 2, as can best be 13 seen best in Fig. 1. Within this dephlegmational operating heat exchanger element 2 the final condensation of the steam takes place. In order to ensure complete final condensation, each dephlegmational operating heat exchanger element 2 is provided with at least one fan 7. The condensate produced by the condensation at the heat exchanger elements 1 and 2 is collected below the dephlegmational operating heat exchanger element 2 by a condensate removal line 8. At the ridge of the dephlegmational operating heat exchanger element 2 the inert gases remaining after final condensation are removed by an inert gas line 9.
The heat exchanger elements 1 and 2 with o0 their corresponding distributing line 4, collecting lines 5 as well as condensate removal line 8 and inert gas line 9 are connected to the o o separate support frame 10 of each individual sector S, as can be seen in Fig. 1. In the shown embodiment, this support frame 10 not only serves to support the heat exchanger elements 1 and 2 and the corresponding lines, but also simultaneously serves as a support or foundation for the cooling tower shell which, in the shown embodiment, is 14
I
shaped like a closed polygon and is in the form of a steel construction made of individual shell segments 11. By employing individual support i i frames 10 for the individual sectors S as a U foundation or support for the cooling tower shell Scomprised of shell segments 11 the conventional separate foundation for the cooling tower shell is eliminated.
As can be seen in the plan view of Fig. 2, the longitudinal dimension of the heat exchange elements 1 and 2 are adapted to the size of the base surface area in order to optimally use the space provided and are therefore different within each circular arrangement. The design of the individual ribbed tubes, there roof-shaped design, Sthe bottom width of the heat exchanger elements 1, and the design of the chambers provided at the ~ridge or at the bottom portion are however identical.
The dephlegmationally operating heat exchange elements 2 are also comprised of identical, in the i shown embodiment essentially square elements which are provided with one or a plurality of fans 7.
As a function of the correspondingly needed surface area they can be arranged on the inner, 15 the central, or the outer circular portion of each sector S. In the embodiment shown in Figures 1 and 2, an arrangement with a surface area ratio of approximately 5 to 1 of condensationally operating to dephlegmationally operating heat exchanger elements is represented, whereby the dephlegmationally operating heat exchanger elements are arranged on the inner circular portion of the sectors S. The suction chambers 9a for the inert gases provided at the ridge of the pitched roof-shaped dephlegmationally operating I ,heat exchanger elements 2 are arranged in parallel to the steam distributing chambers la at the ridges of the pitched roof-shaped condensationally operating heat exchanger elements 1.
0i While in the embodiment according to Fig. 1 the heat exchanger elements 1 and 2 are arranged 00'°0. in a common horizontal plane, the second 0 0 embodiment according to Fig. 3 shows an arrangement of the heat exchanger elements 1 and 0 a 2 within one sector S in a plane which ascends from the center outwardly. With this measure the resistance of the natural draft cooling tower against lateral winds is improved in a known manner.
16 In the third embodiment according to Fig. 4, a construction design is shown in which the suction chamber 9a at the ridge of the pitched roof-type dephlegmationally operating heat exchanger element 2 arranged in the innermost circular portion of the sector extends radially.
With this design the collecting lines 5 coming from the condensationally operating heat exchanger elements 1 directly lead into the distributing chambers of the dephlegmationally operating heat aIl exchanger elements 2.
I In the fourth example according to Fig. 5 an b be embodiment of the condensationally operating heat exchanger elements 1 is shown in which the radially outwardly extending portions of the 0 o\Oo pitched roof-type design according to the spacial possibilities are extended to the border line of the sector S. In this manner the free or unused o#oo space of the base surface area is reduced.
.The present invention is, of course, in no o oo: way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claims.
